A solution to multiple dependencies problem : http://mostafa-samir.github.io/async-recursive-patterns-pt2/#comment-2522702892

multi-deps.js

function loadMeatOf(name, list) {
    
    var deferred = Promise.defer();
    
    http.get('http://localhost:8080/meta/' + name, function(response) {
        
        var responseBody = "";  // will hold the response body as it comes
        
        // join the data chuncks as they come
        response.on('data', function(chunck) { responseBody += chunck });
        
        response.on('end', function() {
           
            var jsonResponse = JSON.parse(responseBody);
            list.push(name);
            
            // iterate asynchronously over the dependencies
            // you can use WaterfallOver if you want to handle the dependencies in order
            IterateOver(jsonResponse.dependencies, function(dep, report) {
                loadMetaOf(dep, list)
                .then(function() {
                    report();
                });
            }, function() {
                deferred.resolve();
            });
